I sold some second hand electrical goods to a guy who came to my home to collect them. Even though he missed the first arranged time and was half hour late for the second, I gave him five stars, but he gave me four stars without any reason. I was slightly annoyed by it but let that go.
But then a week after the sale, he contacted and accused me of selling a faulty good. I didn't, I always check goods before selling and they were fine. I told him that and also argued that of all we know it could've been broken by him. After all he contacted me one week later! I've sold several electrical goods before and no one had problems, while his reviews show some of his buyers weren't happy with what he sold (yup I know, red flag). So I pointed that fact, but he doesn't seem to get my points and keeps contacting me calling me a cheating lier.
Now I am worried that he knows my home address and he might turn up to hassle me and even attack me. Or he might do that while I am out and about with my baby! 
It was only £10 so I can just return the money but then I also don't want to see this guy again or share bank account details!
Really regretting letting know my address like that and this whole experience puts me off from using Shpock again.
Am I being paranoid? If you were me, what would you do?
